would result in the following for each matching file:

	 1)  The library would be KRUNCHed to 5 members.
	 2)  All member files would be sent to LST:.
	 3)  The library directory would be listed.
	 4)  The prompt,  "PRESS ENTER FOR NEXT FILE "	would  be

	 5)  NULU would wait for the user to press RETURN  before

	 Note that if you add or delete any lines in an NCF file,
	 that  will completely foul up any jump commands in  that
	 file.	That's a bug, not a feature.

     -Z  TOGGLE CONSOLE
	 Syntax: -z

	 This  command toggles all output to the console  device.
	 That  is,  if this command is issued once,  all  console
	 output is shut down,  with the exception of the  special
	 commands  listed  below.   Issue it again,  and  console
	 output will be re-enabled.
~
     -'  PRINT TEXT
	 Syntax: -' "text to print"

	 Use this command to print text to the console, no matter
	 what the condition of the console output toggle. Text to
	 be  printed  must be enclosed in  quotes.   The  opening
	 quote	MUST  be present,  but the closing quote is  only
Š	 necessary to delimit any following commands.
~
     -"  PROMPT AND CHAIN TO PREVIOUS MODE
	 Syntax: -mode to chain to -" "prompt" -failure mode

	 My  method of syntax diagramming falls utterly short  of
	 describing this command, I know.  Let's take it one step
	 at  a time.   This command allows the NULU programmer to
	 specify the mode to which he wishes to pass a parameter,
	 prompt the user for that parameter,  and to also specify
	 actions to be taken if no response is received from  the
	 user.
~
         Foò example:
               "-ù *lbò -ï -¢ "opeî whicè library¿ ¢ -ê 65535"

	       Would result in:
	 1.  A directory listing of all files with a type of .LBR
	 would	be  listed to the console device if  the  console
	 were toggled on.
	 2.  The OPEN LIBRARY mode would be transparently entered
	 just long enough for NULU to take note of it.
	 3.  The console would be prompted with the message:

	 (CR, LF)
	 OPEN WHICH LIBRARY?
~
	 and NULU would wait for the user to enter a line of text
	 NOT EXCEEDING the length of the prompt(!).   If the user
	 entered and RETURN by itself or a null line,  the prompt
	 would reappear on the next line.   If the user entered a
	 valid line,  the first word on that line (delimited by a
	 space,  tab,  etc.)  would be passed to the OPEN LIBRARY
	 mode and the balance of the line would be ignored.   If,
	 on the other hand,  the user entered an ESCAPE  followed
	 by  a	RETURN (1bh,  0dh) the commands after the  prompt
	 would	be executed and control would be passed  to  line
	 number 65535, almost surely a non-existent line, thereby
	 terminating the current NCF file.

	 Some  commands which normally accept  parameters  cannot
	 receive  parameters  from  this mode  because	they  are
	 decodeä differently®  Theså includeº
         -:¬ -;¬ -l¬ -n¬ -x¬ -y¬ ->
~
     -:  WAIT FOR RETURN
	 Syntax: -: -failure mode

	 This  command	will  force NULU to wait for  the  RETURN
	 (0dh) character to be input to the console device.  If a
	 RETURN is received, the balance of the command line will
Š	 be ignored.   If a ^C is entered, the remaining commands
	 on the line will be executed.
~
     -;  COMMENT
	 Syntax: -; comment about this kludge of a JCL

	 This  command	will  cause  NULU  to  ignore  all   text
	 appearing after the command on the same physical command
	 line.
